Radiobiology, Radiation Dosimetry and Protection

At the end of this course, the students should be able to: 1. demonstrate clarity in communicating the biological basis of radiation protection; 2. describe international standards and practices for safety in all applications of radiation for medicine and industry. Students should carry out measurements using radiation dosimetry equipment; 3. describe principles of operation of radiation dosemeters; and 4. apply principle of radiation protection in radiology and other settings.
